A scientist wrote down the steps to perform a chemical experiment, but they are out of order. Help the scientist by rearranging

his steps in the correct order. Measure out 0.3 grams each of the solids, lead nitrate and potassium iodide. Watch mixture change from clear to a yellow solid and record observations. 1 Measure 100 ml distilled water into each of two beakers. 1 Write a science report detailing results and conclusions. Dissolve each solid in a separate beaker of water. Pour both solutions into one container and slowly stir. Create a presentation and share findings with peers. Predict what happens when lead nitrate reacts with potassium iodide.​

What is chemistry and what types of questions do chemists try to answer
Reil [10]

Answer:

Chemistry is the branch of science that deals with the identification of the substances of which matter is composed; the investigation of their properties and the ways in which they interact, combine, and change; and the use of these processes to form new substances.

They answer questions like,  like "What makes up this material?," "How does this material change when heated or cooled,?" What happens when I mix this material with another material,?" and "What rules determine how materials change in different situations?" What makes up Chemical X?

Phosphorus-32 has a half-life of 14.0 days. Starting with 4.00 g of 32P, how many grams will remain after 84.0 days ?
Lelu [443]
T₁=84 d
t₂=14 d
m₁=4 g

n=t₁/t₂
n=84/14=6

m₂=m₁/2ⁿ

m₂=4/(2⁶)=0.0625 g

0.0625 grams will remain after 84.0 days

he rate constant for this zero‑order reaction is 0.0130 M ⋅ s − 1 at 300 ∘ C. A ⟶ products How long (in seconds) would it take f
s2008m [1.1K]

Answer:

188 s

Explanation:

We are told the reaction is second order respect to A so we know the expression for the rate law is

rate = - Δ[A]/Δt = k[A]²

where the symbol Δ stands for change, [A] is the concentration of A, and k is the rate constant.

The integrated rate law for this equation from calculus is

1 / [A]t = kt + 1/[A]₀

where  [A]t is the concentration of A at time t, k is the rate constant, and [A]₀ is the initial concentration.

Since we have all the information required to solve this equation lets plug our values

1 / 0.280= 0.0130x t  + 1 / 0.890

( 1 / 0.280 - 1 / 0.890)M⁻¹ = 0.0130 M⁻¹ ·s⁻¹t

t = 188 s
